Is it possible to disable IPv6 (or IPv4)?

[juha-h]

One user of my Android app asks if it is possible to disable IPv6. In config there is sip_transports, but didn't find ip_protocols for SIP messages. Is there some means to do that?

Not sure if it helps but you can run baresip binary with -4 or -6 params to force IP version.

Thanks, I didn't notice those. There is also parameter

-n <net_if> Specify network interface

which does have corresponding config parameter net_interface.

Is there some reason, why there can't be net_af config parameter or could it be added?

I gave it a try and it seems to be working.
